Bug 393083

Description David Williams 2012-10-29 14:04:22 EDT

First noted this odd behavior in bug 340991. And it still happens, where once or twice a week our automated unit test job fails right away complaining it can not find "pkill" ... which should be "built-in"?! 

Such as see 
https://hudson.eclipse.org/hudson/view/Eclipse%20and%20Equinox/job/ep4-unit-mac64/84/console


Marking as "minor" since easy to work around ... I just restart the job manually, and it works ok that next time. 

Not sure what could cause this ... disk being "spun-down" for power saving and not yet spun-up when the job starts? ... but thought it deserved documenting here in case its a known issue or gets worse. 

It would be worse for us if I wasn't sent a text message each time our job fails :) so I can re-start it right away. [just because of how I've set up our code, its not part of hudson]. It would have more impact if it wasn't noticed for hours and hours and then the test would be "late".
